AXAYACATL, the name of a species of fly, common in Mexico, about the lake; the eggs of which being deposited in immense quantities, upon the rushes and corn-flags, form large masses, which are taken up by fishermen and carried to market for sale. This caviare, called ahuahtli, which has much the same taste with the caviare of fish, used to be eaten by the Mexicans, and is now a common dish among the Spaniards. The Mexicans eat not only the eggs, but the flies themselves, made up together into a mass, and prepared with saltpeper.
